INAUGURATION Project Reflection
In this project we were given a map of the National Mall. On this map there seemed to black, circular smudges on it. Those smudges turned out to be groups of people showing up for Obama's first inauguration. It was our job to find out how many people were at the national mall for the inauguration.
First, we found that a road apart of the national mall was 2.7 miles. This same road was 12 inches on our map, so we found that the scale was 12 in. to 2.7 mi. We then simplified this ratio so 1 in. to 0.2 mi. We then measured the radii of the smudges in inches. Afterwards, we converted these inches into miles. Afterwards, by using the formula for an area of a circle (2πr), we found the areas of these smudges. The sum of all of these areas was 0.2069 miles squared. After some conversion, we found that this equaled 5,768,040 feet squared. After a little research, we estimated that one person took up one square foot of space. So, our answer was that we 5,768,040 people at the inauguration. I feel that this number is wrong because we made a person take up too little space. If we had made a person take up 1.5 square feet, I feel that we'd have a more reasonable answer.
